IMPROVEMENT IN TRACK-LIFTERS.

Specification forming part of Letters Patent No. 147,162, dated February3, 1874; application filed July 25,1873.

To all whom it may concern:

Be it known that I, WILLIAM HENRY PEN- ROSE, ofthe United States Army,have invented a new and useful Improvementin Track-Lifters and I dodeclare' that the following is a true and accurate description thereof,reference being had to the accompanying drawings, and to the letters ofreference markedthereon, and being a part of this specification, inwhich my invention is shown in perspective.

This invention has for its object to furnish a light and cheap device bymeans of which the sunken ties in a railway-track may be readily liftedand sustained in an elevated position while being` tamped up; and tothis end it consists in a pair of crossed grappling-levers, for graspingthe tie, suspended by links at their upper ends from a swiveled clevissuspended in a slot in the end of a simple lever pivoted in a standardrising from a pedestal, which rests on the ground outside the track.

In the drawing, A represents a curved simple lever pivoted at a to astandard, B, mounted on a pedestal, C. The end of the lever is slotted,as at b, to receive a T- headed bolt, c, to'

which is swiveled a clevis, D, in whose jaws are pivoted the upper endsof two links, E, whose lower ends are pivoted to the arms of a pair ofcrossed levers, F, or grapnels, whose lower ends are serrated to grasp across-tie. G is a pawl, pivoted at d in the extremity of the slot oflever A, its lower end being sharpcned, to engage with the surface ofthe crosstie.

The operation of the device is as follows: The pedestal is placed on theembankment, just outside the end of the tie that is to be raised, andthe grappling-levers engaged with the sides of said tie, with the toe ofthe pawl resting upon it. The lever A is then depressed at the outerend, when the tie and a section of contiguous track will easily beraised; at the same time the inner end ot the lever recedes from thetrack, dragging the pawl with it 5 and, on releasing the pressure on theouter end of the lever, the toe of the pawl is immediately forced intothe surface of the cross-tie,

which is suspended by the levers in its elevated position from the endof lever A, whose descent is arrested by the pawl, which has now becomea strut, to support the said lever A.

Where the width of the embankment is not sufcient to allow the pedestalto be placed outside the ties, the former may be placed between two tiesinside the rails, the levers turned to grasp the sunken tie, and the toeof the pawl to rest upon a tie beyond the slinken one.

The bend or curve of the lever A should be strengthened by a tie-rodreaching across the open part, enabling a lighter section of iron to beused wit-hout risk of ilexure.

What I claim as my invention, and desire to secure by Letters Patent,is-

The lever A, pivoted in the standard B of the pedestal C, the crossedlevers F, suspended by the links E E and clevis D from the end of thelever A, and the pawl G, suspended from the end thereof, substantiallyas and for the purpose set forth.
